Product Marketing & Growth
I’m Alex Stern, a senior product marketing and growth leader. My work connects positioning, international launches and customer growth, bringing Product, Marketing and Commercial teams together to drive adoption and revenue.

I have 12+ years in marketing across healthcare, sports and B2B—from building a startup’s first marketing function to leading national campaigns and international product launches.
I ask direct questions, join the dots and turn customer insight into clear positioning, campaigns and tools teams can use. Comfortable setting direction and getting stuck into the copy, creative or deck myself.
British by background, Berlin by choice. Usually happiest in the water or on a bike.
